Precision-manufactured to tight tolerances, this M6 x 143mm Hex Head Cap Screw features a nominal diameter of M6 and a substantial 143mm length for deep engagement. The head boasts a 16mm width for robust wrenching capabilities. Fabricated from Aluminum 6061-T6, it exhibits excellent tensile strength (290 MPa), yield strength (241 MPa), and a low density (2.7 g/cm³), making it ideal for weight-sensitive assemblies. Its inherent corrosion resistance ensures longevity in various environments, from marine to aerospace. The hex drive allows for high torque application without stripping.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Select the appropriate mating hole and ensure threads are clean and free of debris. 2. Hand-thread the screw initially to prevent cross-threading and confirm alignment. 3. Tighten the screw using a calibrated torque wrench to the recommended specification for Aluminum 6061 fasteners, typically around 6.2 Nm for an M6 screw in an aluminum mating surface.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Over-tightening | Utilize a torque wrench set to the appropriate specification for the material and thread size to prevent stripping threads or deforming the fastener/mating component. |
| Using standard steel tools on aluminum fasteners | Employ tools made of hardened steel or specialized aluminum wrenches to avoid galling or damaging the softer aluminum threads. |
